Islamophobia has risen markedly in Germany, a study published on Wednesday showed, underscoring the tensions simmering in German society after more than one million migrants, mostly Muslims, arrived last year.

Every second respondent in the study of 2,420 people said they sometimes felt like a foreigner in their own country due to the many Muslims here, up from 43 percent in 2014 and 30.2 percent in 2009.

The number of people who believe Muslims should be forbidden from coming to Germany has also risen, the study showed, and now stands at just above 40 percent, up from about a fifth in 2009.

The study was conducted by researchers at the University of Leipzig in co-operation with the Heinrich Boell Foundation, the Rosa-Luxemburg Foundation and the Otto-Brenner foundation.

The influx of migrants has fuelled support for the anti-immigrant Alternative for Germany (AfD) party that wants to ban minarets and the burqa and has described Islam as incompatible with the German constitution.
